• You may write in this test book as scratch paper. Grid paper is also provided
at the back of the test book.
• You will find a formula sheet at the beginning of this test book. You may tear
it out of your test book to use while taking the test.
• For each question, choose the answer you think is best.

An Introduction to the MCA
The Minnesota Comprehensive Assessments are reading, mathematics and
science tests that help schools and districts measure student progress toward
the state’s academic standards. The grades 3–8 mathematics assessments
became operational in 2011 as the Minnesota Comprehensive AssessmentsSeries III (MCA-III) and are aligned to the 2007 Minnesota Academic
Standards. In 2012, the science assessments became operational as the
Minnesota Comprehensive Assessments-Series III (MCA-III) and are aligned
to the 2009 Minnesota Academic Standards. In 2013, the grades 3-8 and 10
reading assessments are aligned to the 2010 Minnesota Academic Standards
as the Minnesota Comprehensive Assessments-Series III (MCA-III). In 2014,
the grade 11 mathematics assessment is aligned to the 2007 Minnesota
Academic Standards as the Minnesota Comprehensive Assessments-Series III
(MCA-III).
The Purpose of the MCA Item Samplers
An item sampler is not a complete test. It contains a smaller number of the
items that students will see on a full-length test in the spring. The MCA Item
Samplers were developed to familiarize students and teachers with the format
of the MCA and the kinds of items that will appear on them.
This MCA Item Sampler is not a real test. It should not be used to predict
how well students will do on the tests. However, students may feel more
comfortable with the tests if they have reviewed the Item Samplers prior to
the test.
How the MCA Item Samplers Were Created
The Item Samplers mirror the format of the MCA. The
student directions, segment layouts, and answer sheet each
reflect the way the test will look in the spring, except that the
Item Sampler is shorter than the actual test. As with all MCAs,
the reading passages and the math and reading questions
have been thoroughly reviewed by Minnesota teachers prior to
testing. Minnesota students have answered these questions

previous tests.

Grade 11 Teacher’s Guide
The distribution of question types and their aligned content selected for the Item
Sampler generally reflects a range of items from each strand in the Minnesota
Academic Standards. Whenever possible, the Item Samplers have the following
designs:
Math:
•
•
•
•
Two segments
o All Grade 11 segments allow for the use of a calculator.
o The actual MCA has four segments.
Approximately nineteen multiple-choice items
Five gridded-response items
Formula sheet
The Contents of This Teacher’s Guide
The Answer Key identifies the answers and solutions to the questions. It
also identifies the strand/sub-strand/benchmark from the Minnesota
Academic Standards for the question.
State Standards & Test Specifications
The Item Samplers are primarily intended to familiarize teachers and students
with the format of the MCA. The best preparation for the content of the MCA
is done as a part of your curriculum planning. When doing that, reference the
Minnesota Academic Standards and the test specifications for the MCA. For further
questions about the MCAs, email us at [email protected].
